Five Whys Root Cause System Effectiveness: A Two Factor Quantitative Review, Barbara A. Key

Masters Theses & Specialist Projects

Several tools exist for root cause analysis (RCA). Despite this however, many practitioners are not obtaining the quality improvement desired. Those turning to literature for guidance would find most of the information resides in case studies with anecdotal outcomes. Since 5 Whys analysis has been one of the more pervasive tools in use, this study sought to add to the root cause analysis body of knowledge by investigating tool support factors. While studied in conjunction with 5 Whys, the support variables lend themselves to other root cause analysis tools as well. The purpose of the study was to utilize a …

An Engineering Approach To Industrial Research And Development Of Pillows, Wesley Patterson

Mahurin Honors College Capstone Experience/Thesis Projects

Comfort during sleep, though taken for granted, involves a great amount of research and engineering. Few give it a second thought, but nearly one-third of a person’s life is spent with their head on a pillow, thus making them a point for increased quality. Having been approached by a tier-1 bedding manufacturer, a team of both mechanical and electrical engineers was been tasked with the goal of creating a valid research tool that the customer, Tempur-Sealy, will utilize in the company’s research and development of high-end pillows. The team sought to tackle this project utilizing tools and knowledge gained throughout …

Optimization Of Process Parameters In Micro Electrical Discharge Machining (Edm) Of Ti-6al-4v Alloy, Farshid Alavi

Masters Theses & Specialist Projects

Ti-6Al-4V has a wide range of applications such as in the automotive and aerospace industries. Nevertheless, titanium alloys are very difficult to machine by conventional methods. Micro-EDM is a non-conventional machining method that uses the thermal effect of precisely controlled sparks. Manufacturers are looking for the methods and optimal settings to increase the productivity of micro-EDM in terms of lessening machining time and tool wear. Moreover, surface integrity of the machined area is crucial for some products such as biomedical implants.

The objective of this study was to investigate the effects of the micro-EDM process parameters on response variables, in …

Perceptions Of The Advanced Manufacturing Competency Model (Amcm) For Curriculum Development, Mark Doggett, Muhammad Jahan

SEAS Faculty Publications

The Advanced Manufacturing Competency Model (AMCM) model emphasizes building of competencies at all levels ranging from the shop floor production worker to manufacturing engineers. It consists of different levels of competencies organized hierarchically. The levels are personal effectiveness, academic, workplace, industry-wide technical, industry-sector technical, management and organization-specific competencies.

This paper discusses survey research on the perceptions of manufacturing students, faculty, and industry advisory board members regarding the AMCM. The research evaluated the manufacturing program based on perceptions of the AMCM competencies and the curricular coverage required for entry-level manufacturing professionals. Specifically, the survey sought to answer the following research questions: …

The Application Of Gage R&R Analysis In S Six Sigma Case Of Improving And Optimizing An Automotive Die Casting Product’S Measurement System, Qizheng Ren

Masters Theses & Specialist Projects

With the rapid development of automation technology in automotive manufacturing processes, massive and efficient production is a current trend. Therefore, measurement systems with accurate and automated measuring instruments are sought by automotive companies and suppliers. However, the problematic measuring instruments with unreliable accuracy and stability lead to erroneous measurements and wrong quality decisions that cause manufacturers huge profit losses. An effective method called “measurement system analysis” can be applied to define and eliminate erroneous measurements to ensure adequate reliability. An automotive transmission die casting parts supplier called company T was suffering a serious profit loss due to the erroneous measurements …

A Case Study Of Multiple-Use Finish Electrodes For Die-Sinking Edm, Troy A. Robertson

Masters Theses & Specialist Projects

This study examines the use of one finishing electrode to finish multiple dies without remachining the electrode. The multiple-use electrode finishing experiment in this study addresses technology in the die-forging industry. Methods of manufacturing spherical straight bevel forge gear dies have relied on die-sinking Electrical Discharge Machining (EDM) practices that showed great potential for advancement. The focus of this study is solely on the improvements of electrode use in EDM finishing-processes. The surface finish quality itself is not an area of concern other than maintaining that it does not diminish. The focused concern is maximizing the process by using one …

The Cadet Training Program Versus The Student Certification Program: A Study Of It- Support Training Programs At Western Kentucky University, Michael Courtney Moore

Masters Theses & Specialist Projects

Technology is a critical component of modern-day success. Advancements in technology have improved communication between individuals and companies. Technological advancements have allowed students to earn college degrees online. People who habitually use technology expect a high level of performance and support. As new technologies are implemented, such as complex web services or new operating systems, the dependence for information technology (IT) support grows in demand. Even learning curves can be cumbersome without proper assistance from IT professionals. Companies and institutions must accommodate user needs by implementing fast, efficient, and friendly support. In order to offer optimal customer support, representatives must …
